Question

Which of the following is the most likely reason that a population of mice in a farming area suddenly increases

A.more mice immigrate from neighboring areas
B.fewer mice emigrate to neighboring areas
C.more food is availble as grain is harvested
D.more nesting space is availble as new barns are constructed

Answer 1

​The answer is: C.More food is available as grain is harvested

As more food exist in a certain area, the survivability rate of organisms that could live off that food would be increase. This would lead to a rise in the number of population.

One thing that the farmers can do to address this while saving their products is by introducing the mices' natural predators to the field (such as cats or non-poisonous snakes)

Answer 2

The correct answer should be B.fewer mice emigrate to neighboring areas

Mices are famous for multiplying at enormous speeds. If they don't emigrate, then they can quickly overpopulate a single area of land.
